The IP510/EP510 Series are a patented family of electro-pneumatic
instruments that are used to reduce a pneumatic supply pressure to a
regulated output pressure which is directly proportional to a
two-wire current or three-wire voltage input. This design incorporates
closed loop sensing of the output pressure to achieve excellent
accuracy and vibration stability. They also feature a unique damping
circuit which can be adjusted to prevent overshoot and actuator
hunting. Model selection includes General purpose NEMA 1, and
Water-tight/Corrosion Resistant NEMA 4X (IP65). All models carry
Hazardous Locations and intrinsically safe ratings.
